World News - Smile! A new Canadian tool can re-grow teeth say inventors

Snaggle-toothed hockey players and sugar lovers may soon rejoice as Canadian scientists said they have created the first device able to re-grow teeth and bones. The researchers at the University of Alberta in Edmonton filed patents earlier this month in the United States for the tool based on low-intensity pulsed ultrasound technology after testing it on a dozen dental patients in Canada. "Right now, we plan to use it to fix fractured or diseased teeth, as well as asymmetric jawbones, but it may also help hockey players or children who had their tooth knocked out," Jie Chen, an engineering professor and nano-circuit design expert, told AFP. Chen helped create the tiny ultrasound machine that gently massages gums and stimulates tooth growth from the root once inserted into a person's mouth, mounted on braces or a removable plastic crown. The wireless device, smaller than a pea, must be activated for 20 minutes each day for four months to stimulate growth, he said. ... http://www.breitbart.com

Kuwaitis are voting in parliamentary elections which, for the first time, allow women to cast ballots and stand as candidates. The vote is being held early and comes at a politically turbulent period in the conservative Gulf state's history. A bitter dispute has broken out between the government and opposition MPs over increasing the size of constituencies as a way of preventing corruption. Women make up 28 of the 252 candidates, as well as 57% of the electorate. The BBC's Julia Wheeler in Kuwait says it is a big day for women there - even if they do not get elected this time round - and one they have long campaigned for. However, female candidates hope to secure some seats in parliament, despite standing for the most part against seasoned incumbents....http://news.bbc.co.uk/2/hi/middle_east/5127534.stm

The United States, Russia and other industrial democracies said Thursday they expect Iran to reply next week to an international offer to bargain over Tehran's disputed nuclear program. "We are disappointed in the absence of an official Iranian response to this positive proposal," said a statement from foreign ministers of the Group of Eight industrial nations. "We expect to hear a clear and substantive Iranian response to these proposals" at a meeting scheduled July 5 between the European Union's foreign minister and Iran's nuclear negotiator. Iran has told the EU it will reply at that session, a U.S. official said, but it is not clear whether Iran will give a definitive "yes" or "no." Tehran could ask for changes, or for preliminary talks before any negotiations over the proposal could begin. At the United Nations, Iran's foreign minister said his country would not respond to the offer by next week and still had questions about the proposal...http://abcnews.go.com/International/wireStory?id=2134272

President Robert Mugabe on Thursday rejected international mediation in Zimbabwe's political crisis, saying the southern African state was not on the verge of collapse although its economy was in trouble.Critics accuse Mugabe of running down one of Africa's most promising countries, abusing human rights and hanging onto power by rigging votes in the face of a deepening economic crisis.Speaking at the funeral of one of his ministers, Mugabe -- under pressure from domestic and Western critics to accept U.N. mediation in a crisis largely blamed on his government -- said Zimbabweans were ready to die fighting for their political rights and would never accept subjugation....http://www.cnn.com/2006/WORLD/africa/06/29/zimbabwe.reut/index.html?section=cnn_world

The first railway to Tibet is ready to start operation this weekend, using sealed, oxygenated cars to cope with the thin air and high-tech cooling to keep the frozen track bed stable, China's Railway Ministry said Thursday. The $4.2 billion rail line, which took four years to build, links Tibet's capital of Lhasa to Golmud, a small city in Qinghai province already connected to China's vast rail network.China says the prestige project, which leaders have dreamed of realizing since the 1950s, will help economically develop the poor, restive western region and establish better trade and information links with the prosperous east.Critics say it is part of a larger campaign by Beijing to crush Tibetan culture by allowing a huge influx of Han Chinese migrants....http://www.foxnews.com/story/0,2933,201538,00.html
